充填器对树脂充填Ⅱ类洞后微渗漏的影响
Effect of filler on microleakage after resin filled class Ⅱ cavities
摘要
Abstract
Objective To compare the effects of using three different filling appliances,CompothixoTM resin filler,conventional resin filler,and SonicFill sonic handpiece,on marginal microleakage after auxiliary resin filling of class Ⅱ cavities.Methods A total of 40 permanent molars extracted from the Department of Stomatology,Affiliated Hospital of Shandong Second Medical University(Weifang Medical University Affiliated Hospital)from October 2020 to February 2021 were collected and randomly divided into four groups:A,B,C,and D.Standard class Ⅱ cavities were prepared in the proximal and distal middle of the isolated teeth,filled according to the standard filling requirements of the instruments in each grouping,dissected after temperature cycling and methylene blue staining,and the dye penetration depths of the dental tissues and restorative axial and gingival walls were observed and graded under the body-view microscope to calculate the microleakage degree scores.Results Microleakage occurred in four groups,and tested by the Mann-Whitney U test,the microleakage scores of group A was higher than those of the other three groups(P<0.05);There was no statistically significant difference between groups B and C(P>0.05);The scores of groups B and C were higher than those of group D(P<0.05).Group A had higher microleakage scores than group D(P<0.05),and there was no statistically significant difference between the remaining groups(P>0.05).Conclusion The use of the CompothixoTM resin filler is beneficial in reducing microleakage between the resin and the tooth tissue when compared to conventional filling appliances;Compare with the SonicFill handpiece,the use of the CompothixoTM resin filler is not conducive to the reduction of microleakage between the SonicFill ultrasonic resin and the tooth tissue.关键词
